SEGFECATION forming part o Letters Application tiled September 10, 1355.

To all whom it 71ml/ 00u-cern:

Bc it known that I, VILLLUI Gnrnssnn, a subject of the. Emperor of Germany, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Conveyor; and I hereby declare the following to he a full, clear, and exact description of the same.

My invention relates to a device of novel construction for use particularly in connection with elevators, breweries, and the like, for the purpose of transferring grain from one place to another, though, as will hereinafter more fully appear, its use is not contined to such connection, (the saine only forming a practical adaptation i'or exist-ing requirements) as it is intended that the device shall permit the carrying ont of a system of transportation to cxtreme points at great distances apart and to points between sncli extremes.

It is my object to provide an endless series of receptacles t'or the transportation ot" material of any description, whether solid or liquid, and which shall, whatever the direction Oftlieir movement, he maintained in normallyupright position. It is further my object to provide means l'or controlling the receptacles Q ot' the conveyor, wherel y they shall loe automatically emptied of their contents by capsizing at desired points and readjustcd after being emptied.

To these ends my invention consists in the general construetitni of my device, and also in various details ot' construction and combinations o1' parts, all hereinafter more fully Set fort-h.

Referring to the drawings, Figure l represents my conveyor as passing' from an underground conduit in a street into a warehouse, whence goods are loaded into the receptacles, to he carried to their respective destinations. Fig. 2 shows it in connection with an elevator, from which the grain in hins is directed through chutes into the moving receptacles. Fig. 3 is a view showing a receptacle in elevation, and details of the supporting mechanism for the saine in section; Fig. 4, a plan view ot' a portion of the endless series of receptacles; Fig. 5, a. sectional view of a portion of my device, representing, larger than shown in Figs. l and 2, the receptacles in series and Patent No. 331,951, dated December 8, 1885.

Serial No. 176,654. (No model.)

the means for drawing them; Fig. 6, a view in elevation of two receptacles, showing the means for connecting them; 7, a. section taken through the driving-wheels in engageinent with a receptacle, and through the drivepulley upon the shalt; and Fig. 8 a side elevation ot a portion of the series of receptacles, illustrating various details and the operations eftected by the same.

A denotes the receptacles, which may be of the form shown, or ot' any other forni to render them suitable For their purpose.

Receptacles of the nnmloer required are couneeted together by links r, two of which are pivot-ally adjusted on opposite sides ot' each receptacle upon shafts r", extending laterally therefrom, and to the linlts on adjacent receptacles, hy means of pivots 1"". This construction affords a ilexible connection for the receptacles, which are joined in an endless series,and permits them, in turning upon curves while in motion, as hereinafter described, to maintain their normally upright or vertical positions without interfering with each other.

Upon each shalt r', and loosely mounted thereon, is a wheel, q, the wheels upon oppoy site sides of the receptacles serving to support the latter, when movingou ahorizontal plane,

upon the rails p of a track, B.

C is the driving mechanism, which consists of spokes o, extending radially from a hub, o', supported upon a shalt, D, to rotate with the latter, which is journaled in suitable bearings, as shown in Fig. 7, and actuated hy means of the pulleyv E, con nccted hy a drive-belt, n, with the engine (not shown)` which furnishes the power. The extremity of each spoke o is i'orlzed, as shown, and the mechanism C is set in duplicate upon the shaft D, to cause in its rotation the forked ends of the spokes to engage with the shaft r of the receptacles and drive them in the direction ot' rotation of the device C. \Vhere a short endless series of receptacles moving in a straight line is einployed, a pair of devices, C, at each extremity is all tliatis required, the power'necessary to drive the series heing under all circumstances applied only to one set ci' drive-Wheels C, but where the course of travel is changed, as represented in Figs. l and 2f, a set of the i drive-wheels should he provided at each bend.

IOO

At the point or points where the contents of the receptacles are to be discharged means are provided for effecting their automatic overturning, and the following is a description of the same. Upon the extremity of each shaft r' an oblong guide-block, m, is provided, to extend transversely across the end of the shaft at an angle to the receptacle in its vertical or upright position, and inside of the block m, secured upon each shaft, is a pinion, Z, to engage with a rack, Z', located at the place of discharge, for the purpose of causing, by such engagement, the overturning of each receptacle, the pinions 'upon which engage with such racks. In their partially-capsized positions the blocks m enter between guides F, expanded, as shown, toward their extremities, to receive them and maintain the receptacles thus capsized to insure entire discharge of their contents, even with rapid movement of the conveyer. When the blocks m clear the guides F, the receptacles of their own accord swing back upon their pivotal bearings and resume their normally-upright positions. Besides theguides F, for the purpose above described, similar guides, F', (shown in Fig. 8,) may be provided at the place of loading the receptacles, particularly from a chute, lc, placed obliquely to cause the blocks on to enter between the guides and tip the receptacles to the angle of the chute as they pass underneath the latter.

From the foregoing it will readily be seen that the receptacles, unless purposely overturned to effect the discharge of their contents, are always maintained in a perfectly upright or vertical positionvhether they move in a horizontal or other plane, and thus afford a carrier for conveying liquid as Well as solid material.

Though my in vention,as herei nbefore stated, is intended to supply an immediate Want in connection with elevators and the like, as indicatcd in Fig. 2 ofthe drawings, I design that it shall serve to carry out a system for the general delivery of material, including mail, from a central point, When the pinions upon each receptacle may be set by causing, for instance, to illustrate one way of effecting it, as shown in Fig. 4, the shaft r to extend laterally to varying distances upon the different receptacles to engage with racks Z' and bring the guides F into play, the rack and guides being properly located at the place of the discharge to effect their purpose of emptying the receptacles.

That I claim as new, and desire to secure by Letters Patent, is-

1. A conveyer having flexibly-connected receptacles pivotally hung in their connecting medium in endless series, whereby they are maintained in normally-upright position, and means, substantially as described, for driving the series of receptacles, substantially as set forth.

2. A conveyer having receptacles linked topel the conveyer by their rotation, substantially as described.

4. A conveyer having receptacles linked together in endlessseries, and pivotally hung in the links, to be maintained in normally-upright position, in combination with drivewheels C at opposite extremities of the series, and between the said extremities, to rotate and propel the receptacles, substantially as described.

5. A conveyer having receptacles A,provided with lateral shafts r', links r, flexibly connecting the receptacles at their shafts in endless series, pinions Z upon the shafts, drive Wheels() at` opposite extremities of the series, to rotate and propel the receptacles, and racks Z', to be engaged by the pinions and overturn the receptacles, substantially as described.

6. A conveyer having receptacles A, provided with lateral shafts r', carrying guideblocks m, links 1', flexibly connecting the receptacles at their shafts in endless series, pinions Z upon the shafts, drive-Wheels C at opposite extremities of the series, to rotate and propel the receptacles, racks Z', to be engaged by the pinions and overturn the receptacles, and guides F, to receive the guide-blocks m and maintain the receptacles in their overturned position until released, substantially as described.

7. A conveyer comprising, in combination, receptacles A, provided with lateral shafts r', carrying guide-blocks m, and wheels q, links r, flexibly connecting the receptacles at their shafts in endless series, pinions Z upon the shafts, drive-wheels C, to rotate and propel the receptacles, track B, provided With rails for the Wheels q, racks Z', to be engaged by the pinions and overturn the recep- IOO IIO

taeles, guides F, to receive the guide-blocks m and maintain the receptacles in their overturned position until released. and guides F', to receive the guide-blocks m and effect tipping of the receptacles, the whole being constructed and arranged to operate substantially as described.
